A connectionpin “P” removably extends through the first hole 1H and the second hole4010. The connection pin “P” includes a flange “P1” and a shank “P2”that extends from the flange “P1”. The flange “P1” extends radially andoutward from one end of the connection pin “P”. The flange “P1” islocated within the first hole 1H and the shank “P2” extends beyond thesecond hole 1040. The shank “P2” includes a keyway “P21” defined in thedistal end thereof which can be accessed via the first hole 1H.

Referring to FIGS. 6A to 6C again, when the magazine 1 is to be mountedto the top of the barrel, the magazine 1 is slid along the top of thebarrel to engage the first engaging members 15 with the second engagingmembers 100. The magazine 1 is further secured to the barrel by theconnecting pin “P”, simply pushes the flange P1 toward the keyway P21 toextend the connection pin “P” through the first and second holes 1H,1040. Therefore, the magazine 1 is secured to the barrel in bothhorizontal direction and vertical direction relative to the barrel. Whenthe user needs to remove the magazine 1 from the crossbow 10, the usersimply pushes the keyway P21 toward the flange P1 to remove theconnection pin “P” from the first and second holes 1H, 1040.

The trigger 104D has the first end thereof pivotably connected in theroom 106, and the second end of the trigger 14 extends beyond the secondopening 108 of the case 104A. The passive member 104C is pivotablylocated in the room 106, and located between the press member 109 andtrigger 104D. The passive member 104C is located on the trigger 104D andcontacts the press member 104B. The passive member 104C contacts thedistal end of the second portion of the press member 104B. A secondspring 104G is biased between the passive member 104C and the block 109.The stop 104 is pivotably connected to the case 104A by a first pin 113and is located in the room 106. The first end of the stop 104E normallycontacts the passive member 104C, and the second end of the stop 104Eextends beyond the first opening 112. It is noted that the stop 104includes a U-shaped opening which accommodates the torsion spring 104Fand is used to avoid from touching the lowest arrow 20 to be lowered. Asecond pin 114 is located in the room 1106 and beside the first pin 113.The torsion spring 104F includes two ends which are respectively mountedto the first and second pins 113, 114. The torsion spring 104F providesa force to return the stop 104E to its initial position after the stop104E is pivoted. The press member 104B includes two rods 115respectively extending from two sides thereof. The two rods 115 extendbeyond the case 104A and are movably located in the slot 105. When thetwo rods 115 are shifted to move the press member 104B, the ball 111 ismoved to be engaged with one of the first and second notches 110, 110A.

When in use, the retainer 2 is pivoted upward from the storage space 11,and loading arrows 20 into the storage space 11. The retainer 2 isreleased to press the arrows 20. The string 103B is located close to thefront end 102A and stops the arrow 20 to be lowered toward the barrel102. The string 103B is then pulled in the slot 105 and toward the rearend 102B of the barrel 102. The string 103B then touches and pivots thestop 104E. After the string 103B moves over the stop 104E, the stop 104Ereturns to its initial position by the recovery force of the torsionspring 104F. The string 103B is restricted from shooting by the stop104E. The lowest arrow 20 in the storage space 11 enters into the flightgroove 101 of the barrel 102 because of the string 103B does notrestricts the arrow 20 to be lowered. It is noted that the string 103Bis restricted from shooting by the stop 104E because the ball 111 isengaged with the first notch 110, and the press member 104B and thepassive member 104C contact and restrict each other. Therefore, thepassive member 104C cannot pivot, and the passive member 104C restrictsthe stop 104E to pivot, so as to restrict the string 103B from shooting.

After the arrow 20 is located in the flight groove 101 of the barrel102, the user push the rods 115 to move the press member 104B toward thefront end 102A of the barrel 102 to remove the ball 111 from the firstnotch 110, and the ball 111 is shifted to be engaged with the secondnotch 110A. Therefore, the press member 104B is released, and thepassive member 104C is pivotable. The user then aim the target and pullsthe trigger 104D which pivots the passive member 104C. The pivotalmovement of the passive member 104C releases the stop 104E so that thestring 103B pivots the stop 104E. The string 103B then shoots the arrow20. By repeating the steps mentioned above, the lowest arrow 20 entersinto the flight groove 101 so that the user is able to shootcontinuously.

The case 104A includes a first part 116 and a second part 117 which ismounted to the first part 116 to from the room 106. The first part 116and the second part 117 each have an elongate hole 118, and the two rods115 extend through the elongate holes 118 and are moveable in the slot105 so that the users can conveniently operate the rods 115 as shown inFIG. 7. The movement of the rods 115 controls the movement of the pressmember 104B and shifts the ball 111 to be engaged with one of the firstand second notches 110, 110A.

The present invention also provides the second embodiment and the thirdembodiment of the retainers 4, 6, and the main difference of the secondembodiment and the third embodiment of the retainers 4, 6 from the firstembodiment of the retainer 2 is the way to load the arrows 20. As shownin FIGS. 15 to 20 which show the second embodiment of the retainer 4.The second embodiment of the retainer 4 is located in the storage space11 and resiliently and normally presses the arrows 20. The retainer 4includes a plate 41 and a spring 42. The plate 41 has the first endthereof pivotably connected to the inside of the storage space 11, and apin 5 removably extends through the magazine 1 and extends through thesecond end of the plate 41. The spring 42 is connected to the undersideof the plate 41 and presses the arrows 20 in the storage space 11.Specifically, the spring 42 is a wave-shaped spring or a Z-shapedspring, and has flexibility. Therefore, the plate 41 is able to bepivoted upward as shown in FIG. 19 and extends the spring 42. The plate41 is pulled beyond the storage space 11, and the arrows 20 are loadedinto the storage space 11. The plate 41 is then released to cover thestorage space 11. The plate 41 is positioned by using the pin 5. Thespring 42 presses the loaded arrows 20.

As shown in FIGS. 21 to 26 which shows the third embodiment of theretainer 6. In this embodiment, a chamber 13 formed along the twoinsides of the second section 11B of the storage space 11. The retainer6 is located in the chamber 13 of the storage space 11, and resilientlyand normally presses the arrows 20 in the storage space 11. The retainer6 includes a top board 61 and a protrusion 62 extending from theunderside of the top board 61. That is to say, the retainer 6 is aT-shaped retainer.
